A method for disposing of a slug produced in a hole punching operation on a hollow profile is provided. The method includes the steps of providing a hollow profile; cutting at least one predeterminable hole or slug contour path into the hollow profile by means of a cutting device; leaving a residual web of the hole or slug contour path; moving a receiving device into the hollow profile; moving a punch from a first position into a residual-web-removing second position in such a way that the slug thereby produced is received by the receiving device; and moving the receiving device out of the hollow profile.

The invention is directed to an apparatus and a method for generating separating fissures in a substrate through action of a laser beam having an elliptical beam cross section with a beam spot length in a movement direction along a separating fissure to be generated in the substrate. The apparatus and method are particularly suitable for separating fissures which start or end on the substrate surface. A suitable diaphragm prevents radiation from impinging on the substrate before the start and after the end of the fissure.
